Answer:

The first one is D and the second one is B

Step-by-step explanation:

The first is D because the volume of a cylinder is v = π (pi) times the radius squared times the height of the cylinder.

so (π)(16^2)(7) =5629.73 ft^3

Then 1 ft^3 is = 7.5 gallons of water, so you multiple 5629.73 by 7.5 and round. Which gets you 42223

Lines are perpendicular if they meet at right angle.

Line ${\overline{CD}}$ is perpendicular to ${\overline{AB}}$ vice-versa is not true.

Hence, Option B is correct

Suppose f(x)=x^2. what is the graph of g(x)=1/3 f(x)

saw5 [17]

Step-by-step explanation:

f(x) = x^2

g(x)= 1/3 f(x) = 1/3 x^2

First lets make a table for f(x)= x^2

Lets pick some numbers for x and find out y

x y=x^2

-3 (-3)^2 = 9

-1 1

0 0

1 1

3 9

Now we use the same x values and make a table for g(x)

x $g(x)= \frac{1}{3} x^2$

-3 $g(x)= \frac{1}{3}(-3)^2=3$

-1 $g(x)= \frac{1}{3}(-1)^2=\frac{1}{3}$

0 0

1 $g(x)= \frac{1}{3}(1)^2=\frac{1}{3}$

3 $g(x)= \frac{1}{3}(3)^2=3$

Graph the above table

Find the product of A and B: A= -8+4i, B= 2-5i

Scrat [10]

A= -8 + 4i
-8 - 4i

B= 2 - 5i
2 + 5i

I hope this is correct, these ones are confusing.
